Subject: reiserfs: fix hang on umount with quotas when journal is aborted
From: Jan Kara <jack@xxxxxxx>
Call dquot_drop() from reiserfs_dquot_drop() even if we fail to start a
transaction. Otherwise we never get to dropping references to quota
structures from the inode and umount will hang indefinitely.
